Academic Profile:

2009: PhD, Graduate School of Science, Copenhagen University, Denmark. Title of Thesis: “Integrating measurements, Phenological Models and atmospheric Models in Aerobiology.”

Research Profile:

Carstens research focus around aeroallergens and agricultural air quality. The main research questions are related to the exchange between atmosphere and the vegetation/surface and how meteorology affects this exchange and later the concentration of the species in the atmosphere. The studies species includes pollen (e.g. birch, grasses, ragweed) fungal spores (e.g. Alternaria and Cladosporium), pathogens and air pollutants, especially ammonia.   The research is typically carried out by combining ground based observations (e.g. pollen, fungal spores or ammonia) with mathematical models and data obtained through remote sensing.
